You must select a team from a group of 6 boys and 10 girls. How many ways can you select 2 boys and 5 girls?

Keith_Richards [23]

Using the combination formula, it is found that you can select 2 boys and 5 girls in 2,520 ways.

In this problem, Joao and Elisa would be the same team as Elisa and Joao, hence the order is not important and the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

2 boys are selected from a set of 6.

5 girls are selected from a set of 10.

Hence:

$T = C_{5,2}C_{10,5} = \frac{5!}{3!2!} \times \frac{10!}{5!5!} = 2520$

You can select 2 boys and 5 girls in 2,520 ways.

Z - 6/3 = 4<br><br> what is the answer for the variable?

Nana76 [90]

Answer:

Z = 6

Step-by-step explanation:

To solve this equation, we can do the opposite of -6/3 to isolate Z and get our answer. The opposite of -6/3 is +6/3, so we add 6/3 to both sides.

Z - 6/3 = 4

+6/3 +6/3

Z = 4 + 6/3

Z = 4 + 2

Z = 6

75% is equivalent to 3/4 so you divide 30 by 3 and then multiply by 4 to get get 40.
